Referring to Figs. 1, 8 and 23, the frame of the machine designated ingeneral by 1, including the four corner uprights and the two intermediate uprights secured to the sills, transverse bars between the forward two and rear two upright-s, longitudinal bars 2 and 3 at the sides ofthe top of the frame connecting the uprights, three transverse bars, two of which 5 and 6 are shown connecting the sills and oblique brace bars 8 and 9V securedat their upper end 'to transverse bar 7 and at ytheir lower ends to ltransverse bar 5.

Referring especially to Fig. 24, a. bar 1 0, parallel to intermediate upright has its lower end bent inwardly and secured to said upright; a bar 11, parallel to intermediate upright has its lower end bent outwardly and secured to said upright. The main drive shaft v12, the Vend of which is shown in Fig.y 1 and in plan in Fig. 24 is mounted in boxes secured to bars 10 and 11 and is actuatedby thebelt pulley 13. Said shaft carries a pinion 14, which drives a gear Wheel`15, mounted on a rotatable shaft 16. F

Referring now to Figs. 19, 20 and 23, on the shaft 16 is secured a gear wheel 17, which drives gear wheels 18 and 19 secured on shafts -20 and 21 in the direction of arrows Fig. 19.

On'the shaft 2O are secured the rear wheels 22 and 23 which drives gear whees 24 and 25 secured on rotatable feeder shafts 26.

Referring now to Figs. 1, 2, and 4 ythe chute 27 into the mouth 28 of which' the material to be baled is introduced, has its upper portion formed in the arc of a circle, of which the feeder shaft 26 is the center and its central portion is reversely curved in the arcrof a circle of which the ivot shaft 29 is the center. `The chute 27 1s secured to the frame at its upper and lower end in any suitable manner. The upper and rearward wall of chute 27 has a lurality of slots therein, Fig. 3 through wllfich the feeder arms 30 are driven, in the following manner. The ear wheels 24 and 25have integral with their spokes at equal distance from their centers', a lurality of boxes 31 in which are mounted tiie transverse shafts 32 parallel to feeder shaft 26. To each of transverse shafts32 is secured a .plurality of feeder arms 30. One end of each lof said transverse shafts is provided with a crank arm 33 carryin a' roller 34 which travels in the groove 35 o the stationary cam 36 secured to frame 1 by braces 37. Said cam i is circular excepting the substantially straight 38 playing in slots formed in the ower side ofl `portion as shown in Figs. 1 and 2.

The gear wheels 24 and 25 rotate in direction of arrow (Fig. 2) thereby carrying the transverse shafts 32 and causing the feeder arms, 30, to descend through the chute 27, thereby carrying the straw to a certain point. At vthis point it is necessary that the feeder arms 30 be raised out of the straw instead of continuing their ycircular path. This vertical motion isy effected by the action of theY the chute 27 Fig. 5. The press prongs 38 vare secured togetherv at thelr lower ends by means of the-cross bar `39 and are retained in their position on the pivot shaft 29 by means vradial movement of said press prongs ulp into of guide bar 4() secured to said press pron s, thereby forming a slot 41 which permits o a and out of the chute 27. Rearwar eX- tendlng arms 42 integral with said press prongs have secured thereto a cross bar 43.

orwar'dly extending arms 44 are secured to the ends of said cross bar, said arms having transverse wrist-pins 45 in alinement with the face of said press-prongs. Pitmen 46 are mounted on said wrist-pins and are actuated by gear wheels 47 and 48 at the sides of the4 machine which are driven by gear wheels 24 and 25. It is evident that the revolution of gear wheels 47 and 48 willcause an oscillating movement of press-prongs 38 about pivot shaft 29.. y

Referring now to Fig. 1 the itmen 46, one

`of which is shown are niounte on wrist-pins v49 from gear wheels 47 andA 48. The other end of said pitmen pass through the stationary guides 50 secured to balecliamber 51. Press-prongs 38 are thussuspended on said pitmen. Gear wheels 47 and 48 rotate in directionindicated by arrows in Fig. 1 causing the oints of the press-'prongs'38 .to describe an e liptical path, the upper curveof which corresponds substantially with the curvature of chute 27 as will be readily understood by reference to Figs. 1, 2, and3. show their position at the half-way point of their rearward throw with said press-prongs up into the chute 27. Fig. 3 shows their position at the half way point of their forward ythrow with said press-prongs beneath the chute 27 The revolution of gear wheels 47 and 48 by means of pitmen 46 and guides 50 produce an oscillating and radial movement of pressprongs 38, thereby carrying said pressprongs up into the chute 27 during the rear- Y ward throw and beneath the chute 27 during the forward throw "th-usl forcing the straw into the bale chamber 51. l Guides 50 through which pitmen 46 move in their 'reciprocating movement are provided with anti-friction rollers 52. n v

Referring now to Figs. 4, 1, 5, 6', 23 the wire carrying needles 53 andguard arms 54 will .next be described. 'When the bale chamber 51l is'filled with straw some loose straw may be in the chute 27 above the bale chamber 51. It is'desired that this may be vmoved out of the way and insure a clear passage for the wire carrying needles-53. A

Figs; 1 and 2v transverse shaft: 55 is pivotally. mounted on the upper and forward end of bale chamber 51. A plurality of parallel pairs of guard arms y54 vare secured to said transverseshaft. Each pair of vguard arms 54 terminate at their outer ends in a loop 56, said loop being curved upward in the arc of a circle wlth said transverse shaft as its center. portion of said guard arms being para lel with the upper surface of chute 27 and in alinement kwith slots 57l cut in the chute y27. A transverse rocker shaft 58 is mounted in the hangers 59 fromthe frame 1. Wire carrying needles 53 are secured to saidrockershaft in alinement with slots`60 cut from the chute 27 Fig. 5. Slots 60 are parallel toslots 57. A Means are provided for operating nee-k dles 53 and guard'arms 54 inconjunction,

The s'trai ht said means consisting of crank armsl secured to transverse shaft 55 an arm 68 secured to rocker-shaft 58, a connecting arm 68and cran Yarm 61, said itman rod 63 i rocker-shaft being actuated by shaft 69 by means of crank arm 66 secured on sh aft 69, a pitman rod 67 connecting said crank arm to arm 62 secured on rocker-shaft 58. Said arm 62 and pitman rod 67 being of predetermined lengths to give desired movemerit to-needles. When the bindin mechanism is set `in motion as hereina ter describedshaft 69 is revolved thereby bringing needles 53 tothe u per end of their throw as shownin dot in Fig. 4 thereby carrying the wires into the twisters and retainers As the needles 53 ascend through the chute 27 guard arms 54 by means of arm 68, a pitman rod 63 and crank arm 61 are forced downward into chute 27,1said needles passing through the loo ed portions of said guard arms.

ach wire needle has near its end a slot 64 Fig. 23 in which are mounted two or three .grooved anti-friction rollers 65 Fig. 4 which prevent the wires from catching on the ed e of said slot. p The wires are taken from ree s or sppols passed through the slots 64 and caug t in the retainer hereinafter described.

Referring now to Figs. 1, 2, 3, 25, 26, 27 and 28 the wire spools 255 are sli ped over horizontal spindles 256, said spindles having secured thereto vratchet-wheels 257, said ratchet-wheels having integral therewi tlli lugs 258adapted to engage holes in said s ols in alinement with said lugs and, there yfloclr said spindles to said spools. Spindles 256 are mounted in the sockets 260 integral with the hangers 261 and 262said hangers are secured to the oblique Vbraces 8, and 9 of the frame. Arms 263 are pivotally secured to v the outer ends of hangers 261 and have integral therewith detents 264in alinement with ratchet-wheels 257, said arms terminate at the inner ends in eyes 265.

The wiresare woundon the spools so that as it is used b the machine it will cause said s ools to revo ve in direction of arrow. The

etents 264 normally engage the ratchet- Wheels 257. The ends of the wire are taken from the spools 255, passed throu h the eyes 265 of arms 263 through the s ots 64 of needles 53 and into the retainers. As the bale forms the wires will be drawn down as before explained causing the wires to be drawn taut through slots 64 of needles 53 and "entangled, Before proceeding with the binding mechanism the manner in which the wires are bound around a balefwill be described.

- As the manipulation of both wires is the same, only one will be mentioned. lt will be assumed in this description that the bale chamber 51 is occupied by a bale of straw. After the wire has been threaded through the needles 53, the gearing is put in motion, the needles 53 carry the wire up through the chute, through the wire twisters and into the temporary retainers where the wires are caught and held and when so held `are twisted, out off, caught in the retainerproper, and released from temporary retainer. When the needle retreats it slides along the wire by means of the slot 64 engaging the wire, and when the needle is down to the lower end of its throw the wire occupies substantially the position shown in Fig. 4'. The feeding and pressing parts will be thrown in motion, the bale in the bale chamber recedingv as the new bale forms the wire being drawn down by the formation of the bale as shown in Fig. 17. The feeding and pressing parts being thrown out of gear and the bindingparts in gear (hereinafter described).l The guard arms 54 begin their downward throw, the needles 53 move upward and carry the wire above the bale into the twister wheels 76 and tempora retainer. The next operation is the twisting of the two portions of the wire at (a) Fi 17. These ortions are next severed just a ove the twist (Fig. 18) leaving the wire caught in the retainer-proper', Fig. 11 and in dot Fig. 10. The needles retreat durin the above operation to the lower end of their throw and come to rest in osition shown in Figs. 4 and 1 by means of Ehe bindin mechanism being thrown out of gear with t e main drive gear later described. Y

We will now describe more fully the gearing by which the rocker-shaft 58 pi tmen and ot er parts are actuated commencing with the main drive shaft 12 and referringto Figs. 1 and 24. The drive shaft 12 carries a pinion 14 which drives a gear wheel 15 mounted on a rotatable shaft 16. On the shaft 16 is se-1 be described. Fig. 4 shows `the base plate 74, of the mechanism, secured to the upper forward end of the bale lchamber 51. A plate is secured to the upper face of base plate 74 to inclose or cover the gearing described hereinafter. Beneath the plate 75 are mounted the twister wheels 76 and the ear wheel 77 which drives Athem (Fig. 16).

he upper bearings of twister wheels 76 are communicating with wire passages 79 cut b one rotation of mutilated bevel ,gear 72 ims through plate 7o which register with slots 8O in base p ate 74 shown in Figs-7, 11 and 16. 'lhrough these slots the needles 53v carrythe wires into the twister wheels 76 and temporary retainers hereinafterdescribed. Twister wheels 76 are cut by radial slots 81 of a width a little greater than that of the. binding wire used (Figs. 7, 9, and 16). Said slots are parallell with each other and register, even withtlie slots 79 and 86 in plates 75 and 74, when rotated to that point by gear wheel 77, which is secured on shaft 82 and driven by bevel pinion 73, said shaft being journaled in base plate 74 and the compound boxes 84 on shaft 69 (Fig. 8.)

Referring now to Figs. 17 and 18. Fig- 17 shows the wire as caught in the retainer proper with the end crimped under the edge of the cutter and retainer disk, pulled down over said cutter and retainer disk, down through the forward slot of said cutter and retainer disk, through the: radial slot 81 of twister wheel 76 around the bale and back through the radial slot 81 and through the forward slot of said cutter and retainer disk A86. When each slotcontains two .wires or rather two portions of the same wire, as hereinafter explained, the mutilated bevel gear 72 is given exactly one revolution, its diameter is a multiple of the diameter of bevel pinion 73 preferably four times as great,- ut for purposes later described having cogs on but half its rim. Hence every rotation of mutilated bevel gear 72 imparts two rotations to bevel inion 73 and gear wheel 7 7, said gear whee 77 beine twice the diameter of twister wheels 76 and therefore parts exactly four revolutions to twister wheels 76. When three and one-half revolutions are completed the wires are cut off (Fig. 18). The mechanism for which will be next described (Figs. 9, 10, 11 and 15). The twister wheels 76 have spindles 85 reared from their upper surface, said spindles vbeing to therear of radial slots 81 and having mounted thereon the cutter and retainer disks 86. Said disks having cut inwardly from their circumference two diametrically opposite 'slots 87, each disk having adjacent to the ipper surface of twister wheels 76, a two bla ed cutter bar 88 of which 89 are the cutting edges (Fig. 13). Said cutter and retainer disks overlap the radial slots 81 in twister wheels 76. `The two slots 87 in each of said cutter and retainer disks registering alternately even with radial slots 81. Cutter andretainer disks 86 aie caused to revolve with twister wheels 76 by means of the wire being pulled down over the tops of said v cutter and retainer disks and through the forward slots 87, the wire passing on down through the radial slots 81 of twister wheels 76 (Fig. 15). Means are provided to stop the rotation of cutter and retainer disks 86, atv three and one-half revolutions, the twister wheels 76'continuing` tothe finish of four revolutions, thereby severing the two portions of the wire from the twisted ortions (Fig. 18) by means of theYK sharp e( ges ofradial slots 81 coming iii contact with the cutting edges 89 'of cutter bars 88l Said cutter bars being secured transversely across the under side of cutter and retainer disks 86 with the cutting edges 89 of said cutter bars 88 at a suitable distance from slots 87 of cutter and retainer disks 86, so that the wires will be crimped under the edges of said cutter yand retainer disks and securely lieldby meanshei'einafter described. Said means consisting of a shaft-9() mounted'in the hangers 91 from the plate 75, arms 92 secured on said shaft ytheir lower ends adapted to engage slots 87 in'cutter `and retainer disks 86. A coil spring 95 f on shaft 90 n ada ted to hold arms 92 in engagement with sai( slots.` An arm 93 carrying a roller 94 is secured on shaft 90 (Figs. 4, 7, and 11).

Said roller being inthe path of'cam 96, said cam being integral with mutilated bevel gear 72 and parallel to the circumference of to be revolved with twisterwh'eels 76'in the twisting operation-until saideam 96 disengages said roller atthree and one-half revolutions of twister wheels 76 when s ring 95 forces arms 92 into engagement'with slots 87 of cutter and retainer disks 86 thereby Y' stopping the rotation of'said cutter and retainer disks, the twister wheels 76 finishing the remaining half revolution, thereby severing the wiresand crimping theends of the I -severed ortions under the edges Vof cutter and retainer disks 86 (Figs. 11 and 15 also shown in dot Fig. 10). When the wires are so caught they are securely held within the slots 87 of cutter and retainer disks 86 by means of plates 167 secured on arms 92 and overlapping said slots. f f

Referring now to Figs'. 10, 15, 17, and 18 the relative positions which the wires assume in the twisting operation will be described. In Fig.' 17 the wire vis shown as being caught in the rearward slot of cutter and retainer disk, pulled over and down through the forward slot 87 of cutter and retainer disk 86 and 25 i The twister wheels 76 rotate in direction of through the radial slot 81 of twister wheel 76 around the baley and back through the radial slot 81 of twister wheel 76and forward slot 87of cutter and retainer disk 86. Fig. 18 shows the position of Wire immediately after having been severed. Fig. v10 shows the Wire as passing through the radial slot 81 of twister wheel 7 6and through the forward slot 87 of cutter and retainer disk 86 immediately preceding the twisting operation. The position of wire as shown in dot being as it wi l appear at the finishof the twisting operation. The forward slot yof cutter and retainer disk at the beginning of the twisting operation becoming the rearward slot of cutter Yand retainer disk at the finish of said twisting operation by means of the rotation ofsaid cutter and retainer disk having been sto ped at three and one-half revolutions of said twister wheels as before described. The

Vwires at the finish of the twisting operation are thus always caught in the rearward slot of cutter and retainer disk and are down oversaid cutter and retainer disk as before described 'and as shown inl Fig. 15.

arrow Fig. 15 thereby bringing the wires in the rearward slots of cutter and retainer disk 86 into engagement with prongs 101 from hangers 91 (Figs. 11 and 15)` and consequently causing said wires to be released from said slots. vIt 'is desired that the wires assing through the eyes of needles 53 and t rou h the radial slots 81 shall be held immediate y above the center of the twister wheels 76 during the twisting operation and be released immediately after. To provide for this a temporary retainer is devised (Figs. 7, 11, 12, and 14) consisting of a bar 99 having slots 100 therein secured to hangers 91 on plate 75, said slots being immediately above the center of twister wheels 76. A bar 102 is slidablyl mounted on bar 99 and in said hangers.. Bar 102 is provided with prongs 103 adapted to be moved across slots 100 and to so retain the wires within slots 100 and to release the wires by withdrawing said lprongs. The compound boxes 84 (Fig. 8) Vas mountedtherein a crankshaft 104 which has secured thereto a inion 1.05 which isv intermittently rotated y intermittent gears -106 on the mutilated bevel gear 72, said intermittent gears being integral with mutilated bevel gear 72 and in alinement with pinion 105 on shaft 104. v' The circular stop cam 107, integral with mutilated bevel gear 72, has recessed portions 108 along side of intermittent gears 106 and is in alinement with double cam shoe 109. A pitnian rod 110 is mounted at one end on crank shaft 104 the other end being pivotall secured to lug 111 on bar 102 so as to a ternately drive the prongs 103 on bar 102 across the slots 100 in ar 99 and to Withdraw said prongs by the action of said intermittent gears on said pinpulled ion.- The cam 107 normally engages the double cam shoe 109 and prevents rotation of crank shaft 104, except when the recessed portion registers with said shoe.

Referring now to Figs. 10, 11 and 4 the position of the wires at the finish of the twisting operation after having been released by temporary retainer is shown. Said wires are pulled down ,by the formation of the bale, over the center of cutter and retainer disks, as before eX lained. It is desired that said Wires sha b e 'retained immediately over the center of cutter and retainer disks. To provide for this plates 167 are rovided with pins 168 which norm ally overap cutter and retainer disks 86. Spindles 85 are providedwith pins 169. The wires are thus retained over the centers of said cutter and retainer disks.

A summary of the binding operation with reference to the time ofthe parts contribute ing thereto is as follows z-The gear wheel 71 on shaft 69 is rotated in direction of arrow Fig, 1, thereby carrying the crank arm 66 and mutilated bevel gear 72. Said crank by means of pitmen 67 and arm 62 from rocker shaft 58 forces the wire needles 53 up through the chute 27, thereby carrying the wires into the radial slots 81 of twister wheels 76 through the forward slots 87 of cutter and retainer disks 86 and into the slots 100 of temporary retainer. Simultaneously with the above movement the guard arms 54 are forced downward into the chute 27 by means of arm 68 from rocker shaft 58, pitman rod 63, and crank arm 61, from transverse shaft cam shoe 109 respectively, thereby revent-` ing rotation of shaft 82 and crank s aft 104 respectively. When the needles have been driven to the upper end of their throw and the wires drawn into the radial slots 81 in twister wheels 76 and into the slots 100 of tem orary retainer as above explained, they are eld within said slots during the twisting Voperation by meansof the prongs 103 on bar 102, being moved across the slots 100 in bar 99by the action of intermittent gear106 on pinion 105. The continued rotation of shaft 69 and mutilated bevel ear 72 drives needles 53 and guard arms 54 ack to normal position, brings cam 96 into engagement with roller 94 on arm 93, thereby causin arms 92 to disengage slots 87 of cutter an( retainert .on gudgeon 127 from standard 128, said wheels are completed by revolution of mutilated bevel gear the cam 96, disengages roller 94, thereby permitting sprin 95t0 ur e arms 92 in to enga ement wlth s ots 87 o cutter and retainer isks, thereby stopping the rotation of said cutter and retainer disks and causing the wires to be severed and caught within the slots of'said cutter and retainer disks by the continued rotation of twister wheels 76. The wires being cau ht and held as above explained are released rom temporary retainer by the continued rotation of mutilated bevel gear 72, bringing intermittent gear 106 into engagement with pinion 105.

l It is evident that the bale binding mechanism operates periodically though the main drive shafts rotation is continuous.

A description of the device 'for throwing the feeding mechanism and the binding mechanism alternately into gear with the main driving gear is Yas follows: Referring to Figs. l1, 19, 20, 21, 22 and 23 the shaft 16 is continuously rotated by gear 15 and carries the intermediate gear wheel 17. Said gear Wheel drives the two gear wheels 18 and 19 of equal diameter though not necessarily of the same diameter as gear 17. Wheels 18 and 19 are not keyed to their shafts but are caused periodically to engage said shaft by the means to be described. Shaft 20fhas secured thereto a pair of parallel arms 114, a crankshaft 115 carrying a roller 116 is rotatably mounted in saidarms and parallel to said shaft. A coil spring 117 around said crank Shaft and between said arms urges crank and roller inwardly. An arm 118 is secured to said crank shaft. Detent 119 is secured to the web or one'of the spokes of gear wheel 18, its forward surface with reference to direction of rotation of said ear Wheel (as indicated by arrow Fig. 19 is formed in the arc of a circle with crank shaft 115 as its center and is in alinement with roller 116. Arms -123 are likewise secured to shaft 21 and carry crank shaft 121, which has secured thereto arm 125, and carries roller 122. Gear wheel 19 has secured thereto a detent 1-20 in alinement with said roller. An oscillatlngv lver 126 is pivotally mounted standar being secured to frame 1. One end b of lever 126 is curved upward in the arc of a circle with pivoted'point as its center, the other end c is curved downward in the arc of a circle with pivoted. point as its center. An u wardly extendin arm 129 is secured to sai lever, said arm having at its outer end a slot 130, said slot being curved 1n the arc of a circle with the pivoted point ofsaid lever as its center. A crank arm 131 1s plvotally mounted on gudgeon 127 with the crank portion extending through slot 130. Rod 132 '1s pivotally mounted at its lower end on said crank arm, its upper end passing through a slot in the overhan in arm 133 of standard 128. Rod 133 is mc osed by a spiral compression spring 134 which is confined between the arm 133 and collarr 135 on said rod. Spring 134 thus lkeeps crank in engagement with one or the other end of slot 130 and consequently one or theother end of lever 126 is depressed according to 1 "slide `bar 139 (Fig. 23 and in dot Fig. 1) said slide bar being mounted in guides 140 from frame 1 and having alug 141 secured thereto in alinement with'arm 142 from shaft 69 and being so adjusted that arm 142 willbe brought into engagement with s'aid lug, bymeans of shaft 69 being revolved in the direction of arrow in the binding operation, thereby shifting crank 131 to the right in Figs. 1 and 19, thereby depressing end c of lever 126 so that the rotation of shaft 21 and arm 125 will bring said arm into engagement with curved portions c of lever- 126, thereby by the continued rotation vof shaft 21 causing roller 122 to be lifted above detent 120, thus stopping rotation Aof shaft 21- arm 149l and a collar 151 on said rod. A

pull rod 152 is pivotallymounted at its ends on the crank 131 and gudgeon 144. Arm 153 is secured on shaft 26 and is in alinement with detent 145. VShaft 26 rotates in direction of arrow Fig. 2 and While a bale is forming by the operation of the Afeeding and pressing parts, said'detent remainsv in the upper position in Fig. 1, said feeding and pressing parts continuing in operation until` said detent, is 'thrown down 1n the path of arm 153 by the means to be described.

Referring to Figs. 1, 21, 22, and 23 the shaft 155 is mounted'in a hanger 156 from bale chamber 51 and hanger 157 from the cut in the bale chamber 51 with the points of the prongs of said sprocket wheel extending saasoe through said slot. It is evident that the pasing adapted to be in alinement with arm 160.

A spira compression spring 161 is retained in position between arms 159 and 160 by means of a guide rod 162 passing through slots in saidarms and limiting the movement of arm 160. A slide rod 163 is mounted in the eyes in the guides 164 from hanger 157 and frame 1. v

A pull rod 165 is pivotally secured to arm 147 rom detent 145 and slide rod 163, said slide rod having a collar 166 secured thereto in alinement with arm 160 from shaft 155. In the feeding and 'ressing operation the bales are forced out t rough the bale chamber, thereby rotating sprocket wheel 158 by means of the bale engaging the points of the pron s of said s rocket wheel, thereby rotating s aft 155 W 'ch brings arm 160 mto engage'ment with collar 166 on slide rod 163.

The continued rotation of shaft 155 causes spring 161 to be compressed and slide rod 163 to recede to the right in Fig. 1, thereby depressing detent 145 into path of arm 153 on shaft 26 (shown inFig. 21) the spring 150 normali retainirxzglaid detent in the two p sitions s own. en slide rod 163 carrying collar 166 has been moved to the left (Fi .1) by means of the pull rod 165, arm 143 antidetent 145 mounted on said 'arm engaging the rotating arm 153, the sprin f 161, having urged arm 160 upward out of t e return path of collar 166, the slide rod 163 is permitted to retain its normal osition. The engagement of detent 145 wit rotating arm 153 simultaneously with the movement of arm 143 ull rod 165 and slide rod 163 causes the end of lever 126 to .be depressed into' the path of arm 118, the end c of lever. 126 to disengage arm 125 permittin roller 122 to be urged by s ring 124 into te path of detent 120. and s ide rod 139 to move to the left in Fig. 1, said slide rod carrying lug 141 to a position to be en aged by arm 142 on shaft 69 by means o pull 4rod 152 mounted at its end on gudgeon 144 on arm 143l and crank arm 131, shifting said crank into position shown in Fig. 19, the spring 134 normally retaining lever 126 in the two positions shown in Figs. 1 and 19. Y When lever 126 is shifted to position shown in Fig. 19, by means. of arm 153 ull rod 152 'and detent 145, said detent is t rown to the upper position (Fig. 1) out of the path of arm 153 by means of the inclined portion of detent 145 engaging lug 154 on cam 36 as will be readily understood by reference to Fig. 21. Detent 145 remains in the upper position shown in Fig. 1 until again thrown down by the action of the sprocket wheel 158 as before described.

When end b of lever 126 is so depressed arm 118 by the rotation of shaft 20 is brought into enga ement with lever 126, thereby causing ro er 116 to be lifted above detent 119 thereby stopping rotation of shaft 20 and throwing the feeding and pressing parts out of gear.` When end b of lever 126 is depressed as before described end c is lifted above arm 125, thereby allowin spring 124 to uric roller 122 into the path o detent 120, there y carr ing shaft 21 and starting the binding mec anism in motion. The gear wheel 71 and shaft 69 in the binding o eration rotate in direction of arrow Fig. 1, t ereby bringing arm 142 into engagement with lug 141 and by means of pull rod 138 shifting the lever 126 and arm 143 back to position shown in Fi 1.

A genera? operation of the gear shifting device is as follows z-The shaft 21 carries the gear wheel which drives the binding mechanism. The shaft 20 carries the gear wheels 22 and 23 which drives the feeding and pressing mechanism, consequently the binding mechanism will be started and the feeding and pressing mechanism stopped every time that end b of lever 126 descends so as to engage the end of arm 118, thereby causing roller 116 to be lifted u from in front'of detent 119 on gear 18 whic continues its revolution but shaft 20 comes to rest. At the same time end c of lever 126 is raised thereby releasing arm 125 `and permitting spring 124 to ur e roller 122 into the path of detent 120 whic engages it and thereby starts shaft 21 and the parts contributing to the binding operation, and as is evident the binding mechanism will be stopped and the feeding and pressing mechanism started every time that end c of lever 126 descends so as to engage the end of arm 125, thereby causing roller 122 to be lifted above detent 120 on gear 19 which continues its rotation but shaft 21 cornesl to rest. At the same time that end c of lever 126 descends end b of said lever is raised, thereby permitting roller 116 to be urged into the path of detent 119 which engages it, .thereby starting shaft 20 and the parts contributing to the feeding and pressing operation.

A recapitulation of the operation of the different parts in their consecutive order 1s as follows The material to be baled 1s fed into the mouth 28 of the chute 27. The feeding arms 30 carry it-into the chute to a point from where it is taken by the press prongs 38 and forcedinto the bale chamber 51. The wires having been previously caught in the retainers are drawn down by the formation of the bale. The previously bound bale in the bale chamber recedes as the new bale forms thereby revolvinv the sprocket wheel 158 and causing the ditent 145 to be forced downward into the path of arm 153 which engages it and thereby causes lever 126 to be shifted so as to cause end b of lever 126 t'o be thrown into the path of arm 118 which engages it, thereby causing roller 116 to be lifted out of the path of detent 119, thereby throwing the feeding and pressing parts out of gear. When end b of lever 126 is depressed end c is lifted, thereby disengaging arm 1-25 and allowing 10 s ring 124 to urge roller 122 into the path of etent 120 which engages it, thereby throwing the bindin part in gear. The guard arms 54 move ownward into the chute `27. The needles 53 move upward through the chute and carry the looped wires into the slots of the twister wheels and cutter and retainer disks and into the slots. 100 of the temporary retainer.

T e rongs 103 on bar 102 are moved 2o across s ots 100, thereby retaining the wires within said slots. The cam 96 engages roller 94 and causes arms 92 to disengage the slots of the cutter and retainer disks 86, the guard arms and needles retreating to their normal position. The twister wheels 76 and cutter and retainer disks 86 twist the wires, sever the twisted portions and retain the wires within the slots of said cutter and retainer disks.- The prongs 103 on bar 102 are withdrawn from across slots 100. Arm 142 engages lug 141 thereby shifting lever 126 so that end bdisengages arm 118, thereby A allowing roller 116 to be urged into the path of detent 119 which engages it, thereby starting the feeding and pressing arts in operation. When end b is lifte end c 1s depressed into the path of arm 125 which engages it and thereby causes roller 122 to be lifted up from in front of detent 120, thereby throwing the binding parts out of gear.
